ELECTRIC METAL-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 564,859, dated Jul 28,1896.

Application filed November 8, 1895. Serial No. 568,327. (No model.)

To all whom it may concern:

Be it known that we, HARVEY HILLARD WHITACRE and ANDREW GURTIN WOLFE,citizens of the United States, residing at \Vellsville, in the county ofColumbiana and State of Ohio, have invented certain new and usefulImprovements in Electric Metal-Sep.

arators; and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the let- 'ters of reference marked on the accompanying drawing, whichforms a part of this specification.

Our invention has for its object the separation or elimination of anyiron or steel metallic particles which may be found in fluid, fluidsolutions, or dry materials used in the various arts, such as inpottery-clays, &c. that contain metal particles which interfere in theprocess of molding, and which would discolor the products.

To accomplish this object, our invention consists in the followingconstruction and combination of features, the details of which willfirst be described and the novel points then indicated and claimed.

The drawing illustrates a partial Vertical section and elevation of anapparatus to which we have applied our improvements and which embody ourinvention.

Any fluid or pulverulent mass, of whatever description, containing ironor steel particles therein, is adapted to be acted upon by our apparatusfor the purpose of eliminating such particles.

We have used our apparatus for the separation of metallic particles withthe best results in the following cases: potters clay, brickmakers clay,china-clay, English ballclay, spar, flint, enamels for brick,brickglazes, china-glazes, &c.

A represents the separator-receptacle. This receptacle consists of anydesired shape or form of trough, pipe, or box, having asuitableinduction-pipe B and eduction-pipe O.

D is a series of magnets disposed upon opposite sides of the box, thepoles of which project through the walls of said box A,where they aremade fluid-tight, and are then inclined preferably toward the outlet ofthe box at an angle of about forty-five degrees, more or less. Therelation of the poles E of the magnets D is such that those whichproject from one side of the box are substantially at right angles tothose which project from the opposite side, thereby forming aninterlocking or zigzag disposal of the poles, which provide a tortuousor irregular passage through the separator-box,in order to morethoroughly intercept, attract, and eliminate all the metallic particlesfrom the solution as it passes therethrough. The efficiency of such adisposal of pole-pieceswithin the separator-boxes efiects a morecomplete and speedy separation of the metallic particles from thesolution than is possible where the poles project into the box at rightangles thereto.

F is a tubular slide-valve located at the discharge end of theseparator.

G is a radially-disposed series of magnets, the poles H of which projectinto the pipe and are bent at right angles, as shown, for the purpose ofattractingthe valve F thereto for the purpose of opening it. When thesemagnets Gr are not energizedjthe weight of the valve causes it to falland seat itself.

L is a source of electrical energy, as a dynamo or battery, and I is aseries of Wire connections, connecting the magnets D and Gin series.

K is a switch for opening or closing the circuit.

. The metal-separator magnets D and the valve-operating magnets G aresimultaneously operated, so that the Valve F opens at the same time thatthe apparatus is put in operation.

To remove the separated material from the collector, the switch K isopened and the magnets demagnetized, which permits the material to falloff and sink to the valve-seat. The valve is then opened and a strongcurrent of clear water sent through the pipes, which will wash away theaccumulated material. A separate circuit for operating the valve-magnets may be employed, if desired.

We file of even date herewith cases relatwith a series of magnets thepoles of which project through the sides thereof, and incline toward oneend of the receptacle'at oppositelydiiferent angles, a valve, andmagnets having poles projecting into the receptacle and bent toward thevalve to attract the same.

In testimony whereof we aifix our signatures in the presence of twowitnesses.
